  2. 11. Structure and mechanical properties of dual phase steels : An experimental and theoretical analysis

    Author : Ylva Granbom; John Ågren; Ir Bruno C. De Cooman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dual phase steels; continuous annealing; dilatometry; microstructure; mechanical properties; process parameters; dislocation model; plastic deformation; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik; Mikrostrukturutveckling i avancerade höghållfasta stål;

    Abstract : The key to the understanding of the mechanical behavior of dual phase (DP) steels is to a large extent to be found in the microstructure. The microstructure is in its turn a result of the chemical composition and the process parameters during its production. READ MORE

  4. 12. Ti3SiC2 synthesis by powder metallurgical methods

    Author : Ida Kero; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Materials; Materialteknik;

    Abstract : The MAX phases constitute a group of ternary ceramics which has received intense attention over the last decade due to their unique combination of properties. The Ti3SiC2 is the most well studied MAX phase to date and it has turned out to be a promising candidate for high temperature applications. READ MORE

  5. 13. On the Study of a Liquid Steel Sampling Process

    Author : Zhi Zhang; Pär Jönsson; Anders Tilliander; Seppo Louhenkilppi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallurgical process engineering; Metallurgisk processteknik; Fluid mechanics; Strömningsmekanik;

    Abstract : The liquid steel sampling method is one of the commonly used procedures in monitoring the steelmaking process. Besides it can be used for analyzing the dissolved alloys, hydrogen content and oxygen content, it can be also employed to monitor the inclusion characteristics at the steelmakings. READ MORE

  6. 14. A study of mold flux entrapment and gas entrainment in an ingot casting process

    Author : Jun Yin; Mikael Ersson; Pär Jönsson; Yogeshwar Sahai; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mold flux entrapments; CFD; Gas entrainment; Ingot casting process; Uphill teeming process; Side teeming process; Numerical simulation; Non-metallic inclusions; Metallurgical process science; Metallurgisk processvetenskap; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : The focus of this work is to study the gas entrainment and mold flux entrapments during the ingot filling process based on physical and numerical modelling.The formation of the free surface was investigated in the uphill teeming method, which illustrates a dynamic change at a quasi-steady state.
